从能量的角度看非纯电阻电路是电流做功将电能转化为其他形式的能量(常见的就是机械能),但总是有一部分电能要转化为热能,这就导致了电功必大于电热。此原理就是非纯电阻电路中的考查点,也是中考必考的内容之一。非纯电阻电路最大的难点就是学生不能很好地转换思路,不能灵活应用公式解题。本文对非纯电阻电路的常见考查做了分类整理,具有一定的概括性及代表性,希望可以帮助学生理清
From an energy point of view, a purely resistive circuit is a current that converts electricity into other forms of energy (common is mechanical energy), but there is always a portion of the energy to be converted into heat, which results in a greater electrical work than electricity. This principle is non-pure resistance circuit test point, but also one of the elements in the exam will be. Non-pure resistance circuit is the biggest difficulty is that students can not convert ideas, can not be flexible formula to solve the problem. This article on the non-pure resistance circuit to do a common examination classified, with a certain degree of generalization and representation, hoping to help students sort out
